Abstract: Systems and methods are disclosed herein for recording electrical signals in the presence of artifacts. The system and methods can employ multiple techniques for attenuating large, unwanted artifacts while preserving lower amplitude desirable signals. Aspects that can improve the recording of electrical signals in the presence of larger artifacts include particular electrode placement and spacing, high dynamic range amplification with good linearity, and signal blanking. Combinations of more or fewer techniques can be employed to achieve the desired attenuation of signal artifacts while preserving the desired signal. The systems and methods are suitable for recording neural signals in the presence of electrical stimulation signals.

Abstract: A method of processing a useable particulated nepheline syenite including providing particulate nepheline syenite with a maximum first grain size; milling the nepheline syenite in a ball mill operated substantially dry to produce a dry feed stock with particles less than a given size; and, using an air classifier to remove particles having a second grain size from the feed stock to provide an Einlehner Abrasive Value of less than about 100. In practice the second grain size is less than 5 microns and the distribution profile is generally 4-5 microns. The product produced by the method is, thus, novel.
